<div class="markdown_content"><p><em>Originally created by:</em> scott_cunningham</p> <p>I see you never received an answer. Hopefully you solved this.

<div class="markdown_content"><p>Good morning,<br/> I would have a question for you:<br/> Is there a way to have a conception that opens and then closes when the program starts on the plc?<br/> In my project I have 4 OSCAT timers that at a certain time perform an operation only that every time the application loads on the plc the timers leave.<br/> I would like to create a denied contact that at startup interrupts the timer output to say 5 seconds and then closes.</p> <p>it's possible ?</p> <p>Thank you, Alberto</p></div>
